Process for the production of polyether carbamates useful as deposit control additives for hydrocarbon fuels.

摘要

A process for the production of polyether monocarbamates, useful in hydrocarbon fuels as deposit control additives, from polyether chloroformates and polyalkylene polyamines which provides for the efficient separation of the reaction product mixture into a hydrocarbon phase containing the monocarbamate product and an aqueous phase containing undesirable polyamine hydrochloride by-product utilizes an excess of the polyalkylene polyamine reactant containing a limited amount of water. The process is particularly advantageous for the continuous production of monocarbamate.
